From "feel" to "data": a scientific expression of surface quality

In the past, people often judged whether a part was smooth or not through touch or experience, but with the rapid development of industries such as aerospace, semiconductors, and medical devices, this subjective judgment is no longer sufficient to meet demand. The precision roughness meter has emerged, which can perform high-precision scanning of the micro undulations on the surface of materials, and analyze multiple parameters such as Ra (arithmetic mean roughness) and Rz (height roughness) through professional software, thereby achieving quantitative evaluation of surface quality.

Integrating multiple technologies to create high-precision measurement tools

The current mainstream Tokyo precision roughness meter adopts various measurement methods such as contact probe, laser interference, white light interference, etc. Among them, contact instruments have good stability and are suitable for conventional metal processing parts; Laser and white light interference devices have the advantages of non-contact, fast, and full field measurement, making them particularly suitable for detecting fragile, soft, or complex curved surface samples. The model also integrates AI algorithms and automation platforms, which can achieve one click measurement and intelligent identification of defect areas, greatly improving detection efficiency and accuracy.

Widely used in the manufacturing field

In automobile manufacturing, the surface roughness of the engine cylinder block and piston rings directly affects friction loss and fuel efficiency; In the production of optical devices, the surface of the lens must achieve nanometer level smoothness to ensure clear imaging; In the 3D printing industry, the roughness control of interlayer structure is the core factor determining the strength and accuracy of the finished product. It can be said that wherever there is a demand for high-precision manufacturing, there is the presence of Tokyo Precision Roughness Tester.
